. i e 4 Claims.

My invention relates broadly to syringes and has todo more particularly with a syringe which is especially useful for administration of vaginal douches.

`A particular object of my invention is to provide a syringe which may be employed by or upon a patient in bed without requiring theuse of a bed pan and which will eliminate all danger of soiling bed linen.

`Aw further object is to provide a device of the type referred to which Will have means for retaining the douche fluid in the body as long as desired and will permit controlled withdrawal of such fluid with a minimum of vinconvenience or disturbance to the patient and Without permitting escape of the fluid.

Still another object is to provide a deviceof the type referred to which Will be simple in construction, of a relatively small number of parts, inexpensive to fabricate, easy to cleanse so that the same may be kept in sanitary condition at all times, and generally satisfactory for all thepur` poses desired.

Various other objects and advantages may become apparent as the description proceeds.

Referring now to the drawing forming a part o-f this specification and illustrating a preferred embodiment of my invention:

Fig. 1 is a side elevational View of a syringe embodying my invention;

Fig. 2 is a longitudinal sectional view thereof on an enlarged scale; and

Fig. 3 is a sectional View taken substantially along the line 3-3 of Fig. 2.

The numeral IU represents a collapsible bulb which has a neck portion l2 receiving and communicating with a nipple l5. Said nipple has a restricted portion l5 which is threaded on the outside thereof to engage a female threaded enlarged portion of a tube 2l?. A gasket 2l is pref erably interposed between the enlarged portion I8 and shoulder 22 formed on the nipple I5. The nipple preferably has a flared end 23, to insure a positive coupling with the bulb l0.

'A collapsible bulb 25 has its base portion 26 in abutting relation to the annular shoulder 2l formed on the collar I8.` An annulus 29 extends inwardly from the base portion 26 of the bulb 25,

said annulus 29 seating snugly against the tube 2D, annular channels `3.!) being provided on the inside of the annulus 29 for insuring a snug engagement. At its other end the bul-b 25 is provided with an integral closure disk 32, said disk being perforated to permit the passage of the 55 tube 20 and provided with another aperture to permit the passage of a tube 33. The tube 33 is provided with shoulders 34 and 35 which seat snugly against opposite faces of the disk 32.

The members l5, 25, and 33 are preferably formed of hard rubber or similar material.

A nozzle indicated generally by the numeral 40 and formed preferably of flexible rubber has a more or less conical tip portion 42 with an axial channel 43. This channel is preferablyclosed at the end of the tip portion as at 45 and communi- Cates with the exterior of the nozzle through orifices llt, tapered grooves M being provided on the exterior of the tip @2 in communication with the orices 45. Formed integrally with the tip portion 42 is a rearwardly extending tubular portion 5I) which engages the tube 2li, the end of said tube 20 being enlarged as lat 5i so as firmly to retain the tubular portion 5i!` of the nozzle. The tip portion of the nozzle is also provided with a longitudinal groove 53. l

The nozzle 4@ is also provided with a guard e portion 55, said guard portion being integral with the tip portion 42. The guard portion 55 is prefl erably of an elliptical or oval contour so as to frm a fluid tight seal against the external female parts. The guard portion is perforated to seat an enlarged portion 51 of the tube 33, Which tube communicates with the groove 53.

In the use of the device above described, the bulb IU is removed from the tube l5 and filled with fresh douching fluid and then restored to its position as shown in the drawing. Before the fluid is expelled from the bulb l0 the bulb 25 is compressed. After the `fluid has been forced into the vaginal tract the bulbs are held in collapsed condition for as `long as it is desired to retain the fluid. It will be seen that the guard 55 Will serve to prevent leakage. The bulb will then be permitted to expand and the suction thereby produced will Withdraw the used fluid, said fluid flowing back through the channel 53 and tube 33 into the bulb 25.

It will be seen that devices embodying my invention are not only extremely efficient and convenient to use, but are also highly sanitary, since the bulb Il) will normally contain only fresh uid, the contaminated uid flowing into the bulb 25. Furthermore, the parts of the device may readily be disassembled and thoroughly cleaned.

Various changes coming within the spirit of my invention may suggest themselves to those skilled in the art, and hence I do not wish to be limited to the specific embodiment shown or uses mentioned except to the extent indicated in the appended claims, which are to be interpreted as broadly as the state of the art will permit.

I claim:

1. In a device of the class described and in combination, a pair of collapsible bulbs arranged in longitudinal alined relation, a nozzle, and a tube connecting said nozzle with one of said bulbs, the other of said bulbs being arranged noncommunicatively on said tube between said noz zle and the first mentioned bulb, said nozzle having a guard portion for forming a fluid tight seal adjacent a body orifice, said second bulb being connected with the inner face of said guard portion for withdrawing fluid from said orifice.

2. In a device of the class described and in combination, a pair of collapsible bulbs arranged in longitudinally alined relation, a nozzle, and a tube connecting said nozzle with one of said bulbs, the other of said bulbs being arranged non-communicatively on said tube between said nozzle and the rst mentioned bulb, said :nozzle having a guard portion for forming a fluid tight seal adjacent a body orifice and also having a longitudinal passage communicating with said second bulb for withdrawing fluid from said orice.

3. In a device of the class described and in combination, a pair of collapsible bulbs in longitudinally alined relation, a nozzle having a guard portion for forming a uid tight seal against a body orice and also having a longitudinal external channel, a tubular member connecting said nozzle with one of said bulbs, the other of said bulbs being arranged non-communicatively on said tubular member,A and means connecting said second bulb with said channel whereby fluid may be withdrawn from said orifice.

4. In a device of the class described and in combination, a pair of collapsible bulbs in longitudinally alined relation, a nozzle having a guard portion for forming a fluid tight seal against a body orilioe and also having a longitudinal external channel, and a tubular member connecting said nozzle with one or said bulbs, the other of said bulbs being arranged non-communicatively on said tubular member, said device having a passage extending from said channel to the inside of said second bulb whereby uid may be withdrawn from said orice.
